Accommodating the LHC Charged Higgs Boson Excess at 130 GeV in the General Two-Higgs Doublet Model
arxiv(2024)
摘要
Charged Higgs bosons are common predictions in most extensions of the
Standard Model (SM) Higgs sector. Therefore, their observation would elucidate
the nature of the Higgs sector. Motivated by the ATLAS collaboration's latest
analysis performed with 139 fb^-1 of Run 2 data intended to search
for charged Higgs boson, produced in top quark decay and subsequently decaying
via H^±→ cb, where an excess with a local significance of
3σ is observed at m_H^± = 130 GeV, we discuss here the
possibility of explaining such excess in the context of the general 2-Higgs
Doublet Model (2HDM type-III), after satisfying all theoretical and up-to-date
experimental constraints. We also propose phenomenological scenarios to further
explore the mass region around 130 GeV in the four Yukawa types of the 2HDM
type-III and suggest alternative decay channel H^±→ cs and/or
H^±→ W^± *h to probe the nature of the observed excess (if
it is not a statistical fluctuation). Future searches for H^± will be
critical in confirming or refuting the first hint of a light charged Higgs
boson at the LHC.
